To all whom it may concern.

Be it hnown that l, HERMAN C. lllArsn, a citizen of the United States, and aresident of S ringtield, in the county of Hampden tate of Massachusetts,have invented ers, of which the following is a description.

y invention relates to vehicle doors and particularly to means Afor preventing the vi'- lill of vertical vibration dll semi-circular in form, and its curved ration thereof 'when the tion.

lt has heretofore been the vibration of vehicle vehicle is in mo# roposed to prevent oor-s by interposing a pad of'resilient material or a spring he-l tween the door jamb and the edge of the.

door.l In this way the horizontal vibration of thel door has been largely eliminated but little reduction has been made inthe amount which is caused by the giving of the vehicle body.

An object of my present .invention lis to provide means which both horizontal and vertical vibration of the door, without in any way interfering with its operation.l A

Another object of my vide simple and efficient a resilient pad or louder in position.

@ther objects of my inventionwill appear more fully hereinafter.

VReferring to the drawing, Fig. 1 is an ele-4 vation of the door casing and jar'nb showing in section a small portion of the edge of the door with my improved means attached inventionl is to prothereto, said section beingV talren on .the linev i-i 0f Fig. e.

Fig. 3 is adetail showing a portion of the door jarnb; and Fig. Illis a perspective view ofthe resilient pad andits attaching means. f ln the drawing the plates 10, 11, constitute the door jamb. Theplate 11 as shown in Figs. 2 and-l is provided at with'a depression or recess 13 *Y wardly. As herein .,shown, this recess? is edge is provided with ra marginal flange lt The devicel shown in Fig. d for* tachrnent to the edge of the door comprises a.

substantially U-shaped metallic casing 16' within which is placed the resilient pad 17.

CMJPANY, A CURPURATION 40F neon nnrrnn.

The outer plate 18 of the casing is preferably of less length than the pad'l'i', and the inner length.

-Tlle outer plate 18 is provided with an aperture 20, and the inner plate 19 is provided with a aperture 21 located beyond the extremityof the pad 17 and an aperture with the aperture 20 of plate he means for attaching the device 1h to the edge of the door D comprise prefer ably the screws 23, 24, the former of which passes through the aperture 21 and the latter of which passes through the apertures 20 and 22 in the' plates 18 and 19 and through the resilient pad 17. rlFhe latter screw, therefore, serves not only to secure the -device to to retain lthe pad 17 within its caslng.

'lhe pad 17 is of'substantially the same coniiguration` as the recess or depression 13 and therefore when the door is closed this pad contacts with rthe curved marginal edge or dange of the recess 13. 'lhis contact between the pad and the marginal'edge of the recess occurs at the bottom and top as well as at the inner edge of the recess, and it is be cause of this fact that my improved device is so eh'ective in preventing not only horizontal vibration of the door, but also vertical vibration thereof.l

hile my invention is not limited to the use of 'a semi-circular recess and a semicircular pad, l find this particular conguration to he of particular advantage since, as wilireadily be understood, it results in a self-centering action between ythe pad and recess. This action may be facilitated, if desired, by mounting the pad 17 loosely in its casing, so that it is free to rotate about the screw 2t as a pivot..

lt is obvious from the above that my. improveddevice though of simple and inexpensive construction edects the" desired results in a most ed'ective and reliable manner.

atl claim is:

1. A device of the character. described` comprising a substantially ll-shaped metalouter wall being of less length t t t in plate 19,A I

plate 19 is preferably# of greater env ith

.lll the door, but also lill) ttt and the pad presenting a semi-circular portion projecting beyond said outer Wall', and means for retaining said pad in the casing.

2. Means for preventing the vibration of a vehicle door comprising a door jamb provided with a semi-circular recess extending inwardly from the outer' edge thereof, in combination With a device to be attached to the co-operating edge of the door and coinprising a substantially U-shaped metallic casing, having inner and outer walls and an integral base connecting said Walls, a resilient pad interposed between the inner and out-er Walls of said casing and seating against 15 the base connecting said Walls, the outer Wall being of less length than the pad, said pad presenting a semicn'cular portion which pro- 'jects beyond the edge of said outer wall,

means for securing the device to the edge of the door, and means for retaining the pad within the casing, the semicircular projecting portion of said pad being adapted to be received in the semicircular recess in the door jamb and to contact with the inner, top and bottoni marginal edges of said seinicircular recess when the door is closed, to prevent vertical as Well as horizontal vibration of the door.
